Smart Control System For Solar Home Automation Using Mobile Phone

Abstract:

As the sources of conventional energy are consuming day by day, resorting
to alternative sources of energy like solar and wind energy has become our
main concern. Now a days using solar panel to preserve the solar power as
electricity is one of the most popular way. Solar-powered home appliance
systems are already available in rural as well as urban areas. Solar charge
controller and the load of the battery is the core of the main solar system.
Charge controller plays an important role as the battery’s overall life
depends mainly on it. In this point of view, this project presents designing a
Solar Charge Controller for the Solar Battery and combines it with an
Android device by which one can easily control the function of connecting
and disconnecting the battery and load during battery over charging or
discharging as well as the capacity to control intensity of the home
appliances according to the load of the battery. Mosfets are used as switch
to ON & OFF the battery and load. To control the intensity an optocoupler
and a mosfet are used. Here Optocoupler is used for better isolation.
Instead of using readily available microcontroller board, here Arduino
microcontroller (2560) has been used to make the system cost-effective.
The source code for the Arduino microcontroller is written in Arduino
software. Furthermore, a blutooth device (HC-05) is used to connect with
the android device. The system has been simulated and practically
implemented. Performance study of the system shows that it works
properly within the range 10 meter distance for a 12 V battery providing
2A electricity.
